It was.... thanks!
I tried posting a comment on the BMJ piece as well - don't know if it'll get published.
A lot of my posts disappeared. Especially the ones with facts and links, so I tried facts & broken links, ...
Corrective posts to smart Alec's also disappeared a lot of times.
I also noticed that if I respond via Disques, the link to their comment is multi-personality. Poster-A links to poster-B and often to poster-C.
